Our non-regulated gas storage business owns or controls approximately 130 Bcf – approximately one-third of all storage capacity in Alberta – through our wholly owned 50 Bcf Edson, Alta. facility, contracted long-term capacity of approximately 30 Bcf from a third party, and our 60 per cent interest in CrossAlta Gas Storage & Services Ltd., which operates a 50 Bcf storage facility near Crossfield, Alta.
Our regulated gas storage business, ANR Storage Company, serves our Pipelines division and provides firm and interruptible natural gas storage services to customers on our Great Lakes Gas Transmission and ANR Pipeline systems.
Liquefied Natural Gas (LNG)
With the North American demand for gas forecasted to exceed the traditional basin supply, new sources of gas are being pursued. TransCanada is well positioned to connect markets to LNG and is currently pursuing two proposed LNG projects, which together are capable of regasifying a combined total of 1.5 bcf/d of natural gas into the eastern Canadian and north eastern U.S. markets.
